摘　要: 本文主要针对6063-T1铝型材折弯后出现的褶皱问题进行研究,通过调整铸棒成分,优化挤压、表面处理工艺参数和时效制度等一系列的试验,发现褶皱开裂现象与型材喷涂后硬度过高、断后伸长率下降有关。最终通过调整铸锭成分解决了成品硬度高断后伸长率低的问题,从而消除褶皱缺陷,满足客户需求。

Abstract: This article is mainly aimed at to study the 6063-T1 aluminum bending fold defect. By adjusting the casting bar composition,optimizing extrusion process,accommodatting surface treatment process parameters and controlling the aging rules,we found that the profile fold cracking phenomenon was concerned with the high hardness,low break elongation after spraying. Finally,we solved the problem by adjusting the composition of ingot,and met the customer requirements.
Keywords: bending; fold defect; surface treatment process; aging rules
